Struct Secret 

pub struct Secret(/* private fields */);

A secret string — a token, a key, a webhook secret.

Wiped from memory when dropped, and its Debug is a fixed placeholder so a stray {:?} or tracing::debug!(?x) cannot write it to a log. There is deliberately no Display, Serialize or Clone: getting the value out takes an explicit Secret::expose, which is easy to grep for.
